Keep your basements warm, dry and fully compliant — with Isotherm & Wykamol

As winter sets in and temperatures drop, the performance of below-ground structures becomes even more critical. Cold bridging, damp ingress and poor thermal efficiency can quickly compromise comfort, safety and long-term structural health.

That’s why Isotherm has become one of our best-selling products at this time of year. Its exceptional thermal properties dramatically reduce cold bridging and surface condensation — not only in basements, but also in solid-wall homes, loft conversions, cold internal walls, utility rooms and retrofit projects. Isotherm is widely used across both residential and commercial buildings to improve warmth, comfort and energy efficiency in any area prone to cold spots.

But for a basement to truly perform, you need more than thermal efficiency — you need a fully certified, building-control-approved waterproofing system working alongside it.

Why combine Isotherm with the Wykamol waterproofing system?

Clever Shield proudly supplies the full Wykamol range, trusted nationwide for its proven performance in below-ground protection. Together, Isotherm and Wykamol create a complete system that ensures long-term defence against moisture, cold penetration and structural risk. These systems are also widely used and approved by councils and housing associations throughout the UK, giving additional confidence to architects, project managers and specifiers working on both public and private sector projects.

Here’s why the Wykamol system stands out:

• 100% compliant for Building Control
• Fully meets BS 8102 standards for below-ground waterproofing
• Supported by BBA certifications for complete assurance
• Full suite of Type A, B and C systems

With combined thermal and waterproofing protection, your basement design is not only more efficient — it’s more reliable and more compliant.
